Powerstone Pumice Stone Toilet Bowl Cleaner with Handle (1-pack) - A Reliable and Harmless Solution for Cleaning Limescale Deposits, Mildew & Hard Water Stains on Toilets, Grills, Tiles, Grout & Pools

Used to remove stubborn calcium rings in the toilets. Had tried everything from Blueland tablets to bleach. Nothing removed the staining until this pumice stone. Great find!

Works well and fast shipping

Truly wish I knew about these sooner. So effective with a fraction of the elbow grease required with any other method. Removed months old rings from our toilets we thought were stained forever.

Just when we were at a complete & total loss, I came across this. We have used it twice since we got it & maintained with weekly scrubbing with a brush. We dont use it too often because it is pumice & will wear away at the porcelain in the toilet.

Easy to use & cleans well as described.

This product is great. It tool the yellow ring around my toilet out. My toilet looks new

Totally cleaned up the toilet bowls! As crazy as it sounds I was bummed about the toilet ring I could NOT get rid of; this product totally did the job and my world is calm once again. A little hard work, some elbow grease and your rings and hard water marks are gone. Well worth the money !

I bought this specifically for removing this stain from my toilet bowl but even after wearing down the corners of the stick to a rounded edge, the stain is still there. I got a refund though.

I moved into a rental unit with a toilet that must be 50 years old. It had deep stains from hard water and cleaning attempts. This device, with some elbow grease, got off the brown and copper-colored stains. It did not get off the years of blue-gel toilet cleaner. It took some time to get the right types of scrape movement that didnt feel like I was digging too deeply into the porcelain. I did a first time, and I was pleased to remove the worst of the brown. Ill do a few regular cleanings before I use it again because I want to make sure the cleaning supplies I do dont absorb into the bowl die to any scratches. a good product if you have horrible stains. I love the handy container it comes in for storage. Also, make sure to wet it thoroughly before you use it!

Finally the hard water lines are gone!
